Abstract

In this paper we study the performance of an innovative Frequency Domain (FD) receiver for IEEE 802.15.4a short-range communications. The proposed system takes benefit of the guard intervals which are introduced in the standard between the symbols, so avoiding the need of the cyclic prefix introduction at the transmitter. The proposed receiver strategy is based on the Minimum Mean Square Error (MMSE) criterion and is compared with the classical rake, considering a scenario where a coordinator communicates with several devices in a short range environment. The channel model, which is characterized by severe multipath propagation, has been derived according to the IEEE 802.15.4a recommendations.
